I have deleted default.htm and that caused my tumblr to appear. When I refreshed, the tumblr disappeared and it just shows an index. I have saved the HTML for this web page, but I do not think I need it. Again, do I just need to wait?

Sorry to hear that you're having problems with the Tumblr site. Typicall, DNS changes such as the A record change may take up to 24 hours to take affect. So, as you state, you may simply need to wait. Give it a day, and then let us know if you're still having the issue. Apologies for the delay!
